Corpas was a workhorse in the bullpen during his three years in the majors, from 2006 to 2008 with the Colorado Rockies. He appeared in 189 major league games in that span, after being in 42 games in the minors in 2006 (with an ERA of 0.98 split between two teams). Corpas pitched in the 2007 World Series, giving up no runs in two games. He had replaced Brian Fuentes as the Rockies' closer down the stretch during their remarkable late-season run that propulsed them into the postseason and saved 19 games that year, with a 2.08 ERA. His 2.08 ERA was the lowest relief ERA in Rockies' history. He saved all three of the Rockies' wins against the Philadelphia Phillies in the NLDS, then added a pair of saves as Colorado swept the Arizona Diamondbacks in the 2007 NLCS. However, he lost the closer's job when he posted a 4.52 ERA in 2008.
Corpas was on Panama's roster for the 2009 World Baseball Classic but did not pitch in the Classic. He then showed signs of fatigue in 2009, posting a very high 5.88 ERA in 35 games. He spent time on the disabled list and was sent back to AAA for 3 games. In 2010, he spent the entire season with Colorado, pitching 56 games with a 4.62 ERA and 10 saves, but was released after the season. He signed with the Texas Rangers for 2011 but did not pitch at all that year, and in 2012 was under contract with the Chicago Cubs.
